_x_ others (information only)
Discussion of Problem:
Sometime between August 9 and 23, 1994 the ventilation fan of the
EBBR stopped; the fan guard was clogged with insect remains. The fan was
restarted at 1922 GMT on 23 August. Inspection of the EBBR data does not
indicate any ill affects on the calculated sensible and latent heat during
the period. The fan may have stopped soon before the arrival of the site
operator on 23 August. I cannot suggest flagging the data as incorrect, but
this message should still be attached to the data so that anyone who might
discover something unusual may have some basis for explaining it.
The quantities that are normally affected by stoppage of the ventilation to
the temperature and relative humidity sensors are:
5 minute: tair_top, tair_bot, thum_top, thum_bot, hum_top, hum_bot,
vp_top, and vp_bot
15 minute: rr_thum_r, rr_thum_l, mv_hum_r, mv_hum_l, tair_r, tair_l
30 minute: tair_top, tair_bot, thum_top, thum_bot, hum_top, hum_bot,
vp_top, vp_bot, bowen, e, h
Other observations/measurements impacted by this problem:
see list above
Suggested Corrections of the Problem: (e.g. change calibration factor and
recompute, flag data with this comment, etc.)
Enclose the message above with the data if possible.

Discussion of Problem:
Around 1200 GMT on September 21, 1994 the aspirator fans of the EBBR
intermittently stopped or slowed significantly; the fans were clogged with
insect remains and spider webs. Only a few weeks earlier the same
situation occurred at this EBBR. The 15 minute data reveals that most of
the time the right aspirator fan was the one that failed to work, although
there are times that it appears that the left fan was either not working
also or was the only one not working. Unlike the previous occurrence, the
30 minute flux data does show some indication of this problem, although, as
usual, it is far easier to see in the 15 minute data. The fans were cleaned
out and restarted at 1530 GMT on September 21, 1994. The data listed below
should be flagged as incorrect for the period shown above.

Subject: | SGP/EBBR/E26 - T/RH Check |
DataStreams: | sgp15ebbrE26.a1, sgp30ebbrE26.a1, sgp5ebbrE26.a0
|
Description: | During the month of November 1994, site operations personnel conducted
field comparisons of the temperature and relative humidity sensors in the
EBBRs and the HMI31 portable T/RH meter (with the removable probe). As is
reflected in the home signal output, the automatic exchange mechanism was
disabled in order to conduct the checks.
Measurements were taken every 5 minutes, for a half hour each in the
aspirated radiation shields (the HMI31 was inserted into the EBBR aspirated
radiation shield to provide the same aspiration as the EBBR sensors
received). Measurements of aspirator flow were also recorded. This
information was provided to the mentor. The mentor then compared the field
checks with the data recorded by the EBBRs.
The periods of data and data fields that are incorrect because of the checks
are listed below. Times are those at which the data are reported.
Data Fields
5 minute: tair_top, tair_bot, thum_top, thum_bot, hum_top, hum_bot,
vp_top, vp_bot
15 minute: rr_thum_r, rr_thum_l, mv_hum_r, mv_hum_l, tair_r, tair_l
30 minute: tair_top, tair_bot, thum_top, thum_bot, hum_top, hum_bot,
vp_top, vp_bot, bowen, e, h
5 minute: 1615, 1620, 1625, 1630, 1635, 1640, 1645, 1650, 1655,
1700, 1705, 1710, 1715, 1720, 1725, 1730, 1735
15 minute: 1615, 1630, 1645, 1700, 1715, 1730, 1745
30 minute: 1630, 1700, 1730, 1800
(EDITOR'S NOTE: The following analysis refers to all EBBRs installed in Nov 1994)
Results of the T/RH comparisons:
The combined accuracy of the HMI31 and EBBR temperature sensors
(thermocouples or PRTDs) is +/- 0.4 degrees C. The combined accuracy of the
HMI31 and EBBR RH sensors is +/- 4% for RH less than 80%, and +/- 6% for RH
greater than 80%. The combined accuracy for each pair of EBBR sensors of
the same type is essentially the same as the quantities stated above.
All of the pairs of EBBR sensors show differences that fall within the
stated combined accuracies. Although this sounds wonderful, a few of the
differences are close to the combined accuracy, which, because of the small
differences in temperature being measured (normally smaller than the
magnitude of the combined accuracy) could lead to some incorrect estimation
of sensible and latent heat flux. However, unless there would be substantial
differences of calibration slope of two sensors in a pair, the switching of
height of the sensors every 15 minutes by the automatic exchange mechanism
will remove the offset between the sensors.
The comparisons between the EBBR sensors and the HMI31 T/RH meter showed
much larger differences. The range of differences were: -2.4 to 0.0 degrees
for the thermocouples, -2.1 to 0.1 degrees for the RH probe PRTDs, and -6.6 to
6.7 percent for the RH sensors. Six Thermocouples indicated differences from
the HMI31 greater than the combined accuracy. Seven PRTDs indicated
differences from the HMI31 greater than the combined accuracy. Four RH
sensors indicated differences from the HMI31 greater than the combined
accuracy. The temperature differences (for both thermocouples and PRTDs)
were nearly all of one sign; the HMI31 indicated the greater temperature,
which may suggest a bias in the HMI31 temperature measurement, even though
a dozen differences of +/- 0.2 degrees were measured. Four differences of
zero and only one positive difference (out of 40) were measured. Thirteen of
the 20 RH differences were positive (HMI31 indicating the lower
RH), with the differences near the level of the combined accuracies being
approximately 50% positive and 50% negative. It does not appear that the
HMI31 has a RH bias.
Plots of EBBR sensor/HMI31 differences as a function of time from the
installation of the individual sensors (a range of 10 to 30 months in the
field) shows no obvious pattern of sensor drift with time. This is encouraging. |

Discussion of Problem:
On November 2, 1995 the changeout for annual calibration occurred at E7,
Elk Falls, KS. SEBS unit 9 was removed and unit 12 was installed. Between
1530 and 1930 GMT no data was collected. The soil moisture probes were
shipped dry from the vendor. Site operations did not realize this and
installed them without wetting the bags that hold the soil moisture probes
in soil. The water did not penetrate into the bags of soil. Therefore, some
soil moisture probe outputs were initially offscale. Different soil
moisture probes indicated offscale at different times until 28 November
1995. On 28 November, site operations soaked the soil moisture probe bags
with water, causing the soil moisture data values to come on scale.
No data was collected during the time of the installation on November 2,
between 1530 and 1930 GMT.
The incorrect soil moisture after SEBS 12 was installed affected numerous
data values including:
15 minute: rr_sm1, rr_sm2, rr_sm3, rr_sm4, rr_sm5
30 minute: h, e, ave_shf, shf1, shf2, shf3, shf4, shf5, sm1, sm2, sm3,
sm4, sm5, cs1, cs2, cs3, cs4, cs5, ces1, ces2, ces3, ces4,
g1, g2, g3, g4, g5.
Inspection of the data readily shows which soil moisture probes were
offscale. When one or more were offscale, the e, h, and ave_shf data and the
respective numbered data variables above were incorrect. h and e can be
recalculated using only correct soil moisture probe values and equations shown
in many previous DQRs.

Discussion of Problem:
During numerous periods within the days listed above, individual soil moisture
probes indicated high or offscale, on the dry side. The cause of the
problems is unknown. Data since 9 January 1996 has been correct.
Recalculation of ave_shf, e, and h must be made using only the soil moisture
sets with correct soil moisture values.
Affected data values are (# for probe number):
15 minute: rr_sm#
30 minute: sm#, c_shf#, cs#, ces#, g#, ave_shf, e, h
Sensible, latent, and soil heat fluxes can be recalculated using the soil
probe sets that provide correct data. For example, if soil moisture 2 is
incorrect,
ave_shf = (g1 + g3 + g4 + g5)/4
e = -(q + ave_shf)/(1 +bowen)
h = -(e + ave_shf +q),
If soil moisture 2 and 4 are incorrect,
ave_shf = (g1 + g3 + g5)/3
e = -(q + ave_shf)/(1 +bowen)
h = -(e + ave_shf +q),
If soil moisture 2, 4, and 5 are incorrect,
ave_shf = (g1 + g3)/2
e = -(q + ave_shf)/(1 +bowen)
h = -(e + ave_shf +q),
